Introducing Scoring Impact

As golfers we practice to get better and typically judge performance by the end score on the scorecard. In golf there are no fractions. We typically all remember the putts we missed as chances gone by and overemphasize the importance of the flatstick on the end result. This is likely because putting is the most binary of golfing skills, the ball either goes in or it doesn’t. Does perception match reality?

First let’s introduce the concept of “Scoring Impact”.

Scoring Impact for Strokes Gained Approach

Once you play more than 5 rounds using a shot tracking app like PocketPAR, you get a distribution of scores varying from your best days to your worst days. “Scoring Impact” is a measurement of how various factors explain the variation in scores. We show this impact via a simple correlation plot with a linear fit. An example of this is shown for Strokes Gained Approach vs. Score.

 

Clearly we can see a trend from the SG Approach plot. When the player has a better ball striking day on approach shots, he/she scores better. This intuitively makes sense… but how do we put it into perspective? The impact number in this case is 0.6 or 60%. This means that 60% of the scoring variation can be attributed to Strokes Gained / Lost on Approach shots.

Scoring Impact from Putting

To the left is Strokes Gained Putting impact for the same player. The best fit line certainly shows a relationship in which score improves with putting, however it is not as clear or obvious when looking at the data. In this case, the impact number is just 16%. This is 1/4th the impact of approach shots, meaning the player would be much better off putting in work on approach shots than putting if he wants to see scores improve.

We can expand this approach to all elements of Strokes Gained and even to traditional metrics such as Fairways, Greens, and # of Putts. After reviewing data from several of our power users over various handicap ranges, the summary data is shown in the table below where several trends appear:

  1. For all handicap groups, Approach shots were at the top in terms of impact on scoring.
  2. As handicap increased, so did impact of Driving on overall score.
  3. Putting was the least impactful area on overall score for all handicap groups, except one.
  4. Traditional metrics don’t correlate well with improved scoring.

Tracking traditional metrics is easy, but it doesn’t tell you how to improve. To reveal true opportunities you need advanced shot tracking and stats such as those provided by PocketPAR.

AmaTour Analytics: Champions Circle

I compete on the Golf Channel Am Tour in the Palmer Flight (4-8 handicap). This series follows the golf and how PocketPAR gives insight on tournament play.

Starting off the 2018 season with a win is always a plus, but I’ve found a disturbing trend in my golf…

The round started on 17 for me in the shotgun start format. Three easy holes to start and I made easy, if not frustrating pars. My short game just hasn’t been sharp. A wedge into 17 didn’t make the green and a two-chip on 18 left a 5 footer I was happy to make for par. You have to at least get a birdie look when you’re greenside in two on a par 5.

You know those holes that just don’t fit your eye? Just can’t get comfortable? #2 at Champions Circle is that for me. A tee shot with a narrow shoot favoring a fade makes me uncomfortable. Even if you smash a drive you have a long iron into a well protected green at best. My tee shot is pulled and runs all the way down into a small creek. Take a drop. Still have to lay up. Happy to leave with just a double.

Holes 2 and 3 at Champions Circle

Number 3 would be a great Par 5. It’s a bad Par 4. Into the wind it’s a 230 carry just to reach the fairway, followed by 200+ yards over a creek to a blind green with death left. It’s a bad hole. I smash a drive and a 4hybrid and am still short of the green (but safe). A bad chip leaves me in a tough spot and a 3 putt yields double.

Now this is where strokes gained analysis comes in handy. I’ve just gone +4 over two holes. Time to panic right? Except I know those are two of the hardest holes on the golf course. The field averaged 5.08 and 5.5 on the two holes. Meaning two doubles didn’t lose 4 strokes, it lost just 1.4 stroke to the field. Still not good, but manageable.

Cruise control. I play the next 7 holes at -1. Right back in the tournament with 6 holes to play. Queue the mental mistakes… I’ll make no excuses, I’ve struggled to close out rounds recently. This was no exception.

11. Took 4 shots to get in the hole from 80 yards.
12. Took 4 shots to get in the hole from 5 yards off the green.
13. Loose shot into a hazard.
15. Three putt from 40’.
16. Missed fairway, missed green, missed 5’er for Par.

Just a collection of lost momentum and poor shots. Whether it be a lack of focus or knowing I’m in the hunt, things got shaky, but what got shaky? What part of my game is struggling when the nerves get amped? PocketPAR has the answers.

Strokes Gained scorecard view. Green indicates areas of the green that were good / great during the round,, white indicates average, and red indicates areas and categories where performance was lower than the rest of the round.

Strokes Gained view of the scorecard gives details on the 6 hole struggle. I drove the ball well enough. My approach game left me in bad spots and my putter went cold as indicated by the red / dark red squares.

This is in-line with how I felt during the round. I hit uncommitted shots into the green on 11, 12, and 13. Didn’t feel comfortable with the wind and made half hearted swings.

By the time I got to 13, I felt as if I had shot myself out of the tournament and lost all focus on the putting green with an inexcusable 3-putt. Limped into the house frustrated with my finish.

But I won! How could that be? The reality is that Champions Circle can be a brutal golf course. And while I did all my damage toward the end, the field was struggling with big numbers lurking.

I shot 81. The field average was almost 89. I had gained 7.4 strokes through 12 holes, even with 2 doubles. During my final 6 hole stumble to the clubhouse, I still gained 0.5 strokes on the field.

So I’m happy that my play early in the round carried me, I know the field gifted me this one and I need to get better.

With PocketPAR I know where. If you need me I’ll be committing to iron shots.

PocketPAR on Apple Watch

The most requested feature for PocketPAR has been Apple Watch support and it is finally here. In the latest release, PocketPAR now officially supports Apple Watch both for yardages and for shot tracking.

The Watch extension requires WatchOS4.0+ be installed and is compatible with all versions of Apple Watch. Quickly get yardages to front / middle / back portions of the green.

Track shots by tapping the score button. Your current GPS location will be saved and you will be given an opportunity to indicate your lie and club used.

Select your lie or mark the location of the hole by pressing the pin button. The data is saved and sent to your phone as soon as a connection is available.

We kept it simple. Nobody wants to stare at small maps on their wrist or try to zoom in on a screen of this size. Simple yardages, simple shot tracking.

For more complicated needs (such as editing shots, layup yardages, and scorecards), the data is always right at your fingertips on your phone. We wanted a watch app that allows you to focus on golf while making tracking shots even easier.

Let’s #MakeMoreBirdies.

**Note: There are limitations when using Apple Watch that prevent PocketPAR from forcing GPS data from the watch. In some cases GPS data will come from the iPhone. For more details and work-arounds, please see our blog on Apple Watch Limitations.

Limitations of Apple Watch

Apple Watch is a great innovation and opens up new opportunities when integrated with iPhone golf apps. Unfortunately, it also comes with limitations that dictate the way in which it can be used.

The default behavior of the Apple Watch is to use the iPhone’s GPS location when available (ie. when paired via Bluetooth). This is to conserve battery life and to support Apple Watch Series 1, which does not have integrated GPS. This can be frustrating for golf applications as the yardage from your golf cart or bag does not benefit you if standing over your ball 30 yards away. Unfortunately there is not currently a way to override this feature in software.

This leads to two main ways to utilize the Apple Watch when playing a round of golf with PocketPAR:

1) Keep your phone in your pocket.
Pros: This solves the issue as your iPhone GPS will accurately reflect your position on the golf course and yardages will be correct. This also allows you to mark shots using the interface on your watch and have instant syncing with your iPhone to review marked shots as you play.
Cons: You must keep your phone on you throughout the round.

2) Disable Bluetooth on your phone.
   Pros: Your watch will be forced to use it’s GPS. You are independent of the phone for yardages and can leave your phone in your golf bag or golf cart once the round is initialized.  
Cons: Only applicable to Apple Watch Series 2+ (Series 1 does not have integrated GPS and requires an iPhone for yardages). Any shots marked on your watch will not synchronize with the iPhone until Bluetooth is re-enabled. Some Apple Watch users also experience slower GPS lock times when not paired with the phone as the GPS chip may take time to lock onto GPS satellites from a sleep state.

The short summary at this time is that there is not a simple answer for seamless independence of Apple Watch and iPhone.  This restriction has been raised to Apple and we hope for an eventual resolution, but at this time we are unfortunately stuck with these limitations.

However, despite the limitations, we believe the Apple Watch experience is one that improves the overall functionality of PocketPAR and makes it even easier to track shots on the golf course. We hope to continue to improve the functionality and feature set provided by the watch extension.

Ways to Win: Rickie’s Rout

There is more than one way to win a golf tournament, Ways to Win will break down how the winner did it each week. 

Well if you listened to Johnny Miller this weekend, you would have thought Rickie won ugly, but sometimes its Thursday thru Saturday that wins a golf tournament. In fact, the recent string of victories by Speith, DJ, Hideki, and Justin Thomas have been victory marches on Sundays after blitzing the field early.

Rickie gained 13.5 strokes on the field in the first three days, allowing him to play conservatively down the stretch and still win by 4 strokes on the difficult PGA National.

Ways to Win: Dominant DJ

There is more than one way to win a golf tournament, Ways to Win will break down how the winner did it each week. 

Always the bridesmaid and never the bride…

After several near misses, Dustin Johnson finally broke through and won at Riviera in dominant fashion. Having to wait out the rain and play 36 holes on Sunday, DJ gave early notice to the field that he wasn’t backing up. Incredible play with just one bogey in his first 62 holes, coasting to a 5 stroke victory the rest of the way.

We all know Dustin can bomb it… but what did he do to dominate the field this week? Continue reading “Ways to Win: Dominant DJ”

Ways to Win: Spectacular Spieth

There is more than one way to win a golf tournament, Ways to Win will break down how the winner did it each week. 

After four consecutive top 10 finishes, Spieth re-emerged in the winners circle. The difference? A hot start in brutal conditions as Spieth put himself in position after round one, rather than digging a hole as he has in recent tournaments.

Once in position, Spieth did what Spieth does and separated himself from the field with the flatstick on Saturday. He gained almost 4.8 strokes on the field with the putter while hanging around the middle of the pack in other strokes gained categories on Saturday.

However, it isn’t just the putter that allowed Jordan Spieth to coast to his 9th PGA Tour victory. Jordan Spieth’s iron game has improved on his performance last year to put him back in contention. Let’s take a look at how Spieth’s performance this week compares to the season’s winners… Continue reading “Ways to Win: Spectacular Spieth”
